| Feb 1, 2018 at 23:10 | comment | added | user31481 | A schematic is way more informative than those two photos. I really doesn't see how things are connected and can't check your circuit. (Not that I actually can, but someone else maybe). | |

| Jun 1, 2016 at 22:59 | comment | added | Malachi | OK that's good news - there's hope! Is it possible for you to upload a youtube of the flashing process? I get a lot of clues about how successful my flash is from how the lights blink. (hopefully your CP20xx has some lights... =) | |
| Jun 1, 2016 at 20:06 | comment | added | Rogier Reerink | The blue LED flashes when I turn it on. I'll see if the new modules work. | |
| Jun 1, 2016 at 17:31 | comment | added | Malachi | You should be seeing a blue LED flash when you power it on at least. If not seeing that then I'd say power delivery or a broken ESP8266. I use this to program mine: ebay.com/itm/252225272540 | |
| Jun 1, 2016 at 9:48 | comment | added | Rogier Reerink | Ah. OK! No the custom firmwares don't work either. Although they do upload without an error. | |
| Jun 1, 2016 at 9:46 | comment | added | Malachi | For example your original posted sketch would constitute a custom firmware. If you're using the ESP8266_AT firmware from the site, then yes I would expect AT commands to work (although I have never actually flashed that firmware before =) | |
| Jun 1, 2016 at 6:30 | comment | added | Rogier Reerink | I have downloaded the firmware from the Espressif website, so it wasn't custom. What custom firmwares are there to try?j | |
| May 31, 2016 at 21:12 | comment | added | Malachi | Sorry to hear this. I'm a little surprised to hear you mention AT commands, after flashing custom firmware I would not expect any AT commands to work. One note: not necessarily gonna solve your problem, but get a genuine FTDI based setup - those CPxxx suckers have always added a layer of problems for me. | |

| May 31, 2016 at 18:19 | comment | added | Rogier Reerink | Hi @Malachi. It's been a while, and a struggle. I just can't get it to work! The new firmware was flashed no problem (kind of), but it just won't run my sketches, nor do the default AT commands work. I think it might just be broken somehow, so I have ordered a couple of new ESP-12Fs. Hope they all keep working. | |
| May 27, 2016 at 10:44 | comment | added | Rogier Reerink | Yes, that is 3.3v input from a regulator. It also should have enough power (2A). | |
| May 27, 2016 at 5:39 | comment | added | Jaromanda X | I noticed that the onboard LED of the ESP-12e doesn't light on anymore - looking at the pictures, I hope the power coming in on the barely visible orange wire is 3.3v | |
| May 25, 2016 at 20:09 | comment | added | Malachi | you're welcome -- my ESP8266's have been super finicky, easy to get a bad flash on em | |
| May 25, 2016 at 19:44 | comment | added | Rogier Reerink | Yeah, weird. I don't know who would do that. I will try to flash new firmware and get back to you! Thanks for your help! | |
| May 25, 2016 at 19:41 | comment | added | Rogier Reerink | Yes, the GPIO pins should be connected the right way. Also, I am able to upload to the flash memory. | |
| May 25, 2016 at 19:13 | comment | added | Malachi | wow, a negative for that? Problem isn't even solved yet. rough crowd. | |
| May 25, 2016 at 16:38 | comment | added | JRobert | The output doesn't appear to be able to have come from your code. Are the states of GPIO[0,2,15] appropriate for booting, at boot time? For running from flash, at run time? | |
| May 25, 2016 at 16:02 | comment | added | Malachi | It seems like maybe the firmware itself is crashing. Have you tried reflashing the device a couple of times? | |
